Areas around Oracle Arena were buzzing with activity and anticipation hours before Sunday's decisive seventh game of the 70th NBA Finals between the Cleveland Cavaliers and defending champion Golden State. The Warriors and Cavaliers are deadlocked at 3-3 in the best-of-seven series after two wins by Cleveland, which hopes to become the first team trailing 3-1 to ever rally and win the finals. The first pitch in a Major League Baseball game at the adjacent Oakland Coliseum between the Oakland A's and Los Angeles Angels came only four hours before the late-afternoon tipoff of the championship showdown, with exiting baseball fans and the arriving NBA crowd set to create a traffic snarl of epic proportions.
